This dream took place during the day, and most of this dream involved me walking around a fictional city.
When I was walking by a college on my way to a field by a building, I was ambushed by my former male classmate JC, who was hiding behind the side of the building closest to the field.
Unfortunately for him, my awareness can be pretty good at times, so I was able to see him & react fast enough to block / stop his attack.
